Introduction
Wireless LANs allow mobile computers to communicate wirelessly and to send captured data to a host device in real time. Before a
mobile computer can be used on a Spectrum24 WLAN, the facility must be set up with the required hardware to run the wireless LAN
and the mobile computer must be properly configured. Refer to the documentation that came with the Access Points (APs) for
instructions on setting up the hardware.
To configure the mobile computer, a set of wireless applications provide the user with the tools to configure and test the wireless
radio embedded the mobile computer. The following wireless applications are available on the task tray from the Wireless Application

Operating Mode
Use the Operating Mode dialog box to select the operating mode (Infrastructure or Ad-Hoc) and the country location.
Figure 4-4. Operating Mode Dialog Box
Table 4-5. Operating Mode Fields
Field
Description
Operating Mode
Infrastructure: Select Infrastructure to enable the mobile computer to transmit and receive data with an AP. Infrastructure is the
mobile computer default mode.
Ad Hoc: Select Ad Hoc to enable the mobile computer to form its own local network where mobile computers communicate peerto-peer without APs using a shared ESSID.
Country
Country is used to determine if the profile is valid for the country of operation. The profile country must match the country in the
options page or it must match the acquired country if 802.11d is enabled.
Single Country Use:
When the device is only to be used in a single country, set every profile country to Allow Any Country. In the Options - Regulatory
dialog box (see Figure 4-45 on page 4-38), set the country to the specific country the device is to be used in, and deselect
(uncheck) the Enable 802.11d option. This is the most common and the efficient configuration. It eliminates the initialization
overhead associated with acquiring a country via 802.11d.
Multiple Country Use:
When the device may be used in more than one country, select (check) the Enable 802.11d option in the Regulatory Options
dialog box (see Figure 4-45 on page 4-38). This eliminates the need for reprograming the country (in Options - Regulatory) each
time a new country is entered. However, this only works if the infrastructure (i.e. APs) support 802.11d (some infrastructures do
not support 802.11d, including some Cisco APs). When the Enable 802.11d option is selected, the Options - Regulatory - Country
setting is not used. For a single profile that can be used in multiple countries, with infrastructure that supports 802.11d (including
Symbol infrastructure), set the Profile Country to Allow Any Country. Under Options - Regulatory, select Enable 802.11d. The
Options - Regulatory - Country setting is not used.
For a single profile that can be used in multiple countries, but with infrastructure that does not support 802.11d, set the profile
country to Allow Any Country, and de-select (uncheck) Enable 802.11d. In this case, the Options - Regulatory - Country setting
must always be set to the country the device is currently in. This configuration option is the most efficient and may be chosen
for use with any infrastructure. However, the Options - Regulatory - Country setting must be manually changed when a new
country is entered.
Note that using a single profile in multiple countries implies that there is a common ESSID to connect to in each country. This
is less likely than having unique ESSIDs in each country, this requires unique profiles for each country.
For additional efficiency when using multiple profiles that can be used in multiple countries, the country setting for each profile
can be set to a specific country. If the current country (found via 802.11d or set by Options - Regulatory - Country when 802.11d
is disabled) does not match the country set in a given profile, then that profile is disabled. This can make profile roaming occur
faster. For example, if two profiles are created and configured for Japan, and two more profiles are created and configured for
USA, then when in Japan only the first two profiles are active, and when in USA only the last two are active. If they had all been
configured for Allow Any Country, then all four would always be active, making profile roaming less efficient.
Tap Next. If Ad-Hoc mode was selected the Ad-Hoc dialog box displays. If Infrastructure mode was selected the Authentication dialog
box displays. See Authentication on page 4-7 for instruction on setting up authentication.

MS CHAP v2
Microsoft Challenge Handshake Authentication Protocol version 2 (MS CHAP v2) is a password-based, challenge-response,
mutual authentication protocol that uses the industry-standard Message Digest 4 (MD4) and Data Encryption Standard (DES)
algorithms to encrypt responses. The authenticating server challenges the access client and the access client challenges
the authenticating server. If either challenge is not correctly answered, the connection is rejected. MS CHAP v2 was
originally designed by Microsoft as a PPP authentication protocol to provide better protection for dial-up and virtual private
network (VPN) connections. With Windows XP SP1, Windows XP SP2, Windows Server 2003, and Windows 2000 SP4, MS
CHAP v2 is also an EAP type.
TLS
EAP TLS is used during the phase 2 of the authentication process. This method uses a user certificate to authenticate.

Authentication
Description
CHAP
Challenge Handshake Authentication Protocol (CHAP) is one of the two main authentication protocols used to verify the user
name and password for PPP Internet connections. CHAP is more secure than PAP because it performs a three way handshake
during the initial link establishment between the home and remote machines. It can also repeat the authentication anytime
after the link has been established.
MS CHAP
Microsoft Challenge Handshake Authentication Protocol (MS CHAP) is an implementation of the CHAP protocol that
Microsoft created to authenticate remote Windows workstations. In most respects, MS CHAP is identical to CHAP, but there
are a few differences. MS CHAP is based on the encryption and hashing algorithms used by Windows networks, and the
MS CHAP response to a challenge is in a format optimized for compatibility with Windows operating systems.
MS CHAP v2
MS CHAP v2 is a password based, challenge response, mutual authentication protocol that uses the industry standard
Message Digest 4 (MD4) and Data Encryption Standard (DES) algorithms to encrypt responses. The authenticating server
challenges the access client and the access client challenges the authenticating server. If either challenge is not correctly
answered, the connection is rejected. MS CHAP v2 was originally designed by Microsoft as a PPP authentication protocol
to provide better protection for dial-up and virtual private network (VPN) connections. With Windows XP SP1, Windows XP
SP2, Windows Server 2003, and Windows 2000 SP4, MS CHAP v2 is also an EAP type.
PAP
Password Authentication Protocol (PAP), has two variations PAP and CHAP PAP. It verifies a user name and password for PPP
Internet connections, but it is not as secure as CHAP, since it works only to establish the initial link. PAP is also more
vulnerable to attack because it sends authentication packets throughout the network. Nevertheless, PAP is more commonly
used than CHAP to log in to a remote host like an Internet service provider.
MD5
Message Digest-5 (MD5) is an authentication algorithm developed by RSA. MD5 generates a 128-bit message digest using
a 128-bit key, IPSec truncates the message digest to 96 bits.

Credential Cache Options
If any of the password based authentication types are chosen, then different credential caching options may be specified. These
options allow an administrator to specify when the network credentials prompts appear. The network credentials prompts can be set
to appear; at connection, on each resume, or at a specified time.
An administrator can enter the credentials directly into the profile which permanently caches the credentials. In this case, user login
to the mobile computer is not required. If a profile does not contain credentials entered through the configuration editor, then the user
must login to the mobile computer before connecting.
Caching options only apply on credentials that are entered through the login dialog box.
Figure 4-13. Prompt for Login at Dialog Box
If mobile computer does not have the credentials, the user is prompted to enter a username and password. If the mobile computer
has the credentials (previous entered via a login dialog box), it uses these credentials unless the caching options require the mobile
computer to prompt for new credentials. If the credentials were entered via the profile, the mobile computer does not prompt for new
credentials. Table 4-9 lists the caching options.
Table 4-9. Cache Options
Description
At Connect
If this option is selected, then a user is prompted for credentials whenever the WCS tries to connect to a new profile. If this
option is not set, then the cached credentials are used to authenticate. If the credentials are not cached, then the user is
prompted to enter credentials. This option only applies if a user is logged in.

Table 4-9. Cache Options (Continued)
Description
On Resume
If the On Resume option is selected, an authenticated user is reauthenticated when a suspend/resume occurs. Once the user
is reauthenticated, the user is prompted for credentials. If the user does not enter the same credentials that were entered
prior to the suspend/resume, the user is disconnected from the network. The user may try up to three times to enter the
correct credentials. If the correct credentials are entered, then the network connection remains intact. This option only
applies if a user is logged in.
At Time
Use this option to perform a local verification on an authenticated user at a specified time. The time can be an absolute time
or a relative time from the authentication, the times should be at least 5 minutes intervals. Once the time has passed, the
user is prompted for credentials. If the user enters the correct credentials, the network connection remains intact. If the user
enters the wrong credentials, the user is disconnected from the network. The user may try up to three times to enter the
correct credentials. If the correct credentials are enter, then the network connection remains intact. This option only applies
if a user is logged in.
When a user enters the credentials, the credentials are applied to a particular profile. If a user logs out, all of the cached credentials
are cleared. If a profile is edited, then all cached credentials for that profile are cleared.
The following authentication types have credential caching:
•

IP Address
The Internet is a collection of networks with users that communicate with each other. Each communication carries the
address of the source and destination networks and the particular machine within the network associated with the user or
host computer at each end. This address is called the IP address (Internet Protocol address). Each node on the IP network
must be assigned a unique IP address that is made up of a network identifier and a host identifier. Enter the IP address as a
dotted-decimal notation with the decimal value of each octet separated by a period, for example, 192.168.7.27.
Subnet Mask
Most TCP/IP networks use subnets in order to effectively manage routed IP addresses. Having an organization's network
divided into subnets allows it to be connected to the Internet with a single shared network address, for example,
255.255.255.0.

When the user launches the Log On/Off application, the mobile computer may be in two states; the user may be logged onto the
mobile computer by already entering credentials through the login box, or there are no user logged on. Each of these states have a
separate set of use cases and a different look to the dialog box.
User Already Logged In
If a user is already logged into the mobile computer, that user may launch the login dialog box for the following reasons:
•
Connect to and re-enable a cancelled profile. To do this, a user would:
• Launch the password dialog
• Select the cancelled profile from the profile list
• Login to the profile.
NOTE: Cancelled profiles can also be re-enabled by using the Profile Editor Wizard and choosing to connect to the cancelled
profile. Cancelled profiles are also be re-enabled when a new user logs on.

Wireless Profile Field
When a user launches the login application, the Wireless Profile field has all the wireless profiles that require credentials
available. This currently includes profiles that use EAP TLS, PEAP, LEAP, and EAP-TTLS.
Profile Status Icon
The profile status icon in the dialog (shown next to the profile name) would show one of three states.
• The profile selected has been cancelled.
• The profile selected is enabled but is not the current profile
• The profile is the current profile (always the case for WCS Launched)
Network Username and Password
Fields
The Network Username and Network Password fields are used as credentials for the profile selected/shown in the
Wireless Profile field. Currently these fields are limited to 159 characters.
Mask Password Checkbox
The Mask Password checkbox determines whether the password field is masked (i.e. displays only the '*' character) or
unmasked (i.e. displays the actual text being entered). If the box is checked, the password is unmasked. Unchecking the
box causes the password to be masked. The default state is unchecked to cause masked passwords.
Status Field
The status field is used for displaying status that is important to the login dialog. If the user opens the dialog and needs
to prompt for credentials for a particular profile at this time, it can use the status field to let the user know that the network
is being held up by the password dialog being open.

Tapping OK sends the credentials though WCS API. If there are no credentials entered, a dialog box displays informing the user which
field was not entered.
The Log Off button only displays when a user is already logged on. When the Log Off button is tapped, the user is prompted with
three options: Log Off, Switch Users, and Cancel. Switching users logs off the current user and re-initialize the login dialog box to be
displayed for when there is no user logged on. Logging off logs off the current user and close the login dialog box. Tapping Cancel
closes the Log Off dialog box and the Login dialog box displays.
When the user is logged off, the mobile computer only roams to profiles that do not require credentials or to profiles that were created
with the credentials entered into the profile
The Cancel button closes the dialog without logging into the network. If the login dialog was launched by the wCS and not by the
user, tapping Cancel first causes a message box to display a warning that the cancel disables the current profile. If the user still
chooses to cancel the login at this point, the profile is cancelled.
Once a profile is cancelled, the profile is suppressed until a user actively re-enables it or a new user logs onto the mobile computer.
